| No problem, just drag another search field from the bottom of the screen. Choose a column and condition (equal, smaller, ...) for each field. All of them will be combined with an AND. A search field without specific condition will act as full-text search for "all columns". | No problem, just drag another search field from the bottom of the screen.

| + | ==== Is it possible to create a drop down based on a query? ==== | ||
| + | |||
| + | For example: ''select distinct (S_YEAR) from PERSON_LIST'' | ||
| + | |||
| + | Be careful because distinct queries are usually "slow", because of the force full table scan at the database level. | ||
| + | To use a custom query for a drop down you do the following: | ||
| + | |||
| + | * Add the table/view as data object in the bottom of the VisionX designer e.g. PERSON_LIST | ||
| + | * Change the query in the data wizard in the bottom right corner e.g. add the distinct keyword before the query columns | ||
| + | * Go to your base table where the drop down should be used, define a manual combobox there, and choose PERSON_LIST object from previous step | ||
